I'm looking for the same capability..
My hard drive was wiped, I lost all my data that wasn't backed up, including all my ical events. Now the only place they are stored is on my iPod touch, but I can't work out how to do a sync so that my touch calendar is exported to my MBP.
if I sync with iTunes it will erase all data on the iPod. Any help would be appreciated..
Cheers
